ELECTRIC BELT.

SPECIFICATION forming part of Letters Patent No. 247,461, dated September 20, 1881.

Application filed July 25, 1881.

To all whom it may concern Be it known that I, F. M. HANNA, of Mount Sterling, in the county of Brown and State of Illinois, have invented certain new and useful Improvements in Electric Belts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in electric belts; and it consists in attaching the two metallic pads together by suitable adjustable connections, whereby the pads can be moved nearer together or farther apart, so as to bring them just opposite to each other upon the body, and insulating the connecting parts of the pads from the body by strips of oil-cloth, as will be more fully described hereinafter.

The object of my invention is to provide an electric belt in which the pads can be adjusted relatively to each other, so that one of them can be placed just over the diseased part and the other pad then adjusted just opposite upon the body, so that the current of electricity will pass directly through the diseased part of the body to the other pad.

Figure l is a plan view of the belt, taken from the inner side. Fig.2 is a horizontal longitudinal section of the same. I

A represents a belt, of any suitable mate- 4 rial, which is intended to pass around the body,

and which may be provided at either one of its ends with any suitable fastening. Secured to this belt by means of a strip of oil-cloth, B, are the two pads O D,which are connected together by means of the two strips E, the inner ends of which strips are loosely attached together in such a manner that the pads can he moved freely back and forth by sliding them on each other. These strips pass through slits or openings which are cut in the oil-cloth, and are only held in position upon the belt by the oil-cloth, and by no other means. This oilcloth, being a non-conductor and interposed between thebody and the strips, prevents the electricity from passing from the strips into (Model.)

the body. One of the pads is made of zinc and the other is made of copper, and both of them are made rounding upon their edges, so that they cannot rub or irritate the body where they come in contact with it. Secured to the back of each one of these pads by means of a rivet or any other suitable device is a sheet or washer, I, of oil-cloth, which serves to insulate the pad from the body. The outer ends of the connecting-strips are fastened to the pads by means of hinged joints passing through slits which are made in these washers, and the washers are made sufficiently wide and large to cover the ends of the strips where they project through the oil-cloth B.

The great objection to electric belts heretofore used has been that there has been no way for adjusting the pads so that one of them could be placed just upon the diseased parts and the other one directly opposite, so that the current from one pad would pass directly through the diseased part to the other, and hence a large proportion of the eli'ects of the belt has been lost. Where the belt happens to be too long or two short, one pad can be placed directly over the diseased parts; but the other pad will be placed against the body at such an angle that only a portion of the current will pass through the diseased part. By making the pads adjustable they can be adjusted so that the current will be passed directly through the diseased part.

Having thus described my invention, I claim In an electric belt, the combination of the belt A, the oil-cloth B, which covers the two connecting-strips and holds the pads in place, the two pads being adjustably connected together by suitable strips, and the washers of oil-cloth, which are placed back of the pads, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

FRANCIS M. HANNA.
